We're dividing 50198757 by 651 
The aim is to understand the frequency of 651 in 50198757.

Advancing to step 1:
651 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 651

Moving on to step 2:
50 divided by 651 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Append the next digit (1) from the dividend to 50 and continue with: 501 / 651

Step 3:
If we divide 501 by 651, we get 0 and a remainder of 501.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 501 after subtracting 0 from 501.
Grab the next digit (9) from the dividend, add it to 501, then carry on: 5019 / 651

Let's proceed to step 4:
651 goes into 5019 7 times with a remainder of 462.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 4557 from 5019 leaves us with 462.
Take the next digit (8) from the dividend and append it to 462, then repeat: 4628 / 651

Going ahead to step 5:
When dividing 4628 by 651, we get 7 with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 77.0
The remainder is 71 after subtracting 4557 from 4628.
Take the next digit (7) from the dividend and append it to 71, then repeat: 717 / 651

Advancing to step 6:
The number 651 fits into 717 1 times, leaving a remainder of 66.
The next digit of our result is 1. 
Result so far: 771.0
Deduct 651 from 717 and we're left with 66.
Grab the next digit (5) from the dividend, add it to 66, then carry on: 665 / 651

Step 7:
If we divide 665 by 651, we get 1 and a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 7711.0
The remainder is 14 after subtracting 651 from 665.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 651

Moving on to step 8:
If we divide 147 by 651, we get 0 and a remainder of 147.
Put 0 as the next digit of the answer. 
Result so far: 77110.0
Deduct 0 from 147 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 9:
1470 divided by 651 is 2 with a remainder of 168.
The number 2 becomes the next digit in our result. 
Result so far: 77110.2
Subtract 1302 from 1470 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 10:
1680 divided by 651 is 2 with a remainder of 378.
Record the quotient 2 as the next digit in the result. 
Result so far: 77110.22
The remainder is 378 after subtracting 1302 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Our division results in 77110.22 with a remaining 0.378.
